Avisia is a Feudal World in the Tamahl Sector of Segmentum Obscurus, located in the galactic north. It is one of the many minor worlds in the Imperium of Man whose economy revolves around agriculture, with its main purpose being to produce foodstuffs for the larger Industrial and Hive Worlds of Mankind. The centuries of exploitation have taken their toll, however, and throughout the 41st millennium the planet's production rate has been dropping as the amount of arable land decreases.
